How do you find ceiling rafters from the top of a mobile home?

To find ceiling rafters in a mobile home from the top, first locate the roof's structural layout by accessing the roof area. Use a stud finder to detect the rafters beneath the roof's outer layer, or tap along the roof surface and listen for a solid sound, indicating a rafter's presence. Typically, rafters are spaced 16 to 24 inches apart, so mark their positions as you find them. Ensure safety precautions are taken while on the roof to prevent falls or injuries.
